At the open end of the acinus the lining cells of the latter becomeflattened or cuboidal, and, together with the basement-membrane,are directly continuous with the similar structures forming the walls ofthe narrow intermediate tubule ; the latter succeeds the acinus asthe continuation of the narrow intercellular clefts of several adjacentacini, and, after a longer or shorter course as a delicate narrow-lumened canal, passes into the intralobular tube. The distinctivecharacters of the latter are its larger lumen and the columnar epithe-lium, many cells of which exhibit a distinct vertical striation through-out the peripheral zone next the basement-membrane. The branch-ing intralobular tubes, on emerging from the lobular tissue, join toform the interlobular duct which occupies the connective tissue lyingbetween and holding together the divisions of the glandular sub- Fig. 165.
